This is a great little meter. It not only lets you know when your filter is needing to be changed, but it also lets you keep an eye on your home water supply by showing the TDS going in to the filter. It will definitely make you appreciate and maintain the water filter in your refrigerator!

I love it, so easy to use and gives you the pre and post DI numbers. This totally saves the need for the TDS pen and also works will to make sure the water is in good shape for the hanna calcium checker.

I installed this on my coralife ro di unit in less than a minute. Very simple to use. I have one end after the resin and one before the resin so I know when to change the resin or membrane.

This works great. This came with the RO/DI Plus system that I bought and is reading 5 ppm going into the DI resin and 0 coming out. I also accidentally dropped the whole TDS meter into water, but it still worked just fine after I opened it up and removed the water from the inside!

Installs in one minute and simple to use. Lets you gauge the membrane for when it needs flushing and the DI for when it needs to be replaced.
